2、he telegraph is familiar to most people . This early telecommunications device is credited, as any school student knows, to Samuel Morse, who , in 1844, made the first long-distance electronic communication via his invention, the Morse telegraph. What is not so commonly known is that Morses was not
3、the only telegraph nor he the only such inventor at this time. A rival system, developed by William Cooke and Wheatstone, was patented in England in 1845 and was subsequently adopted for use by British rail companies to enable speedy communication between rail stations.However , the Cooke-Wheatstone
4、 telegraph, which used six wires and a fragile receiver requiring five magnetic needles, proved to be awkward to use, difficult to transport and expensive to build . Morses version used one wire and a receiver of a simpler and stronger design. This is , no doubt, why it became the favored telegraph
5、in many parts of the world, especially the United States, which built a telegraph line along railway tracks crossing the North American continent, linking eastern cities with western frontiers.Morse chose the Magnetic Telegraph Company to handle the parents for his telegraph technology, and within s
6、even years of the appearance of his invention, the company had licensed use of the telegraph to over 50 companies across the US. In 1851, twelve of these companies came together to form the Western Union Company. By 1866, Western Union had grown to include over 4000 telegraph offices, almost all in
7、rail stations.Another early telecommunications device is still very much with us : the telephone. Although the telephone is popularly thought to be the brainchild of one man, Alexander Graham Bell, this is not the whole truth. Phillip Reis, a schoolteacher in Germany, invented a device in 1861 that
8、he labeled a telephone. Reiss invention was limited to transmitting musical tones, however, and could not send the sound of the human voice across the wire.While Reis was working on his invention, Bell and another man, Elisha Gray, were also working toward the invention of the telephone, though by a
9、n indirect route. Both were , in fact, seeking ways of allowing multiple telegraph signals to travel along the same telegraph line - a system known as a harmonic telegraph. Bell worked in Boston while Gray was based in Chicago, and the two were rivals in their area of research. For both inventors, t
10、he perfection of the harmonic telegraph proved too difficult and both, separately but at around the same time, changed plans and started on the development of a telephone. Most interesting of all is the fact that both men applied for a patent to the US Patent Office for their respective telephones o
11、n the same day, 14 February 1876. Bell was lucky enough to have arrived a few hours earlier than Gray and so it was Bell whose name was to be forever associated with the telephone. The harmonic telegraph, incidentally, was perfected by Thomas Edison, best known as the inventor of the light bulb, in
12、1881.Rights to Bells patent (now recognized as the most valuable patent in the history of technology) were offered to Western Union for $ 100 000, with the assumption that the giant telegraph company would be enthusiastic about the new technology. But Western Union disliked Bells design and instead
